Procurement Notes

Verify the specific ordering suffix RTHT against official documentation to confirm packaging details such as tape and reel specifications. Ensure the selected variant matches the required moisture sensitivity level and reflow soldering profile for the intended manufacturing process.

Selection Notes

Select this component when a 1:3 split is required for LVPECL signals up to 800 MHz. Confirm that the input signal levels align with supported standards like LVDS or CML. Verify that the 24-VFQFN package dimensions fit the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the CDCP1803 series of clock buffers. It serves as a high-performance solution for distributing reference clocks in complex electronic systems where signal integrity and precise timing are critical.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the CDCP1803RGETG4, ensuring functional equivalence in terms of output drive strength and input compatibility.
